The FDA recently approved two new prescription medications to treat irritable bowel syndrome with diarrhea. Viberzi (eluxadoline) and Xifaxan (rifaximin) are the two new recently approved medications. Viberzi helps to reduce bowel contractions, which leads to less diarrhea. Xifaxan is an antibiotic which works to change your gut bacteria and reduce diarrhea.
According to the National Institutes of Health estimates that irritable bowel syndrome (IBS) affects up to 15% of Americans, or more than 45 million people. It is believed that only about half of those people have been diagnosed with IBS by a doctor. IBS commonly affects mostly women under the age of 45.
These two medications are believed to be a big step in the effort to find safe and effective treatments for the condition. “I think patients with IBS should be very excited to have more options,” says Lawrence Schiller, MD, program director of the gastroenterology fellowship at Baylor University Medical Center.
